Assassin's Creed IV: Black Flag gameplay trailer

Ubisoft just released a new gameplay video for Assassin's Creed IV: Black Flag and it looks pretty awesome. We get a glimpse of Havana and Kingston as well as one of the many jungles the game will feature. There is plenty of combat, both naval and hand to hand, in the clip, which looks very fluid. Underwater scenes look stunning and show pirates dodging sharks and diving for treasure. It's not clear what the underwater gameplay will look like and I'm interested to see if Ubisoft will put some restrictions on it or if they'll let you go diving out on the open sea.

So far the game looks fantastic, there's just one thing missing: A trailer with a kick-ass song, like Woodkid's Iron for AC: Brotherhood or Imagine Dragon's Radioactive for ACIII.

Please, Ubisoft?
